ECG were distributed as follows: 87% had LBBB, 10% had RBBB, and 3% were indeterminate. Based on the CCS end point, 69% of patients improved, 16% worsened, and 15% remained unchanged. Based on the LVESV WebIn some cardiac resynchronization systems LV pacing is achieved with the tip electrode of the LV lead as the cathode and the proximal electrode of the bipolar RV as the anode. This arrangement creates a common anode for both RV and LV pacing. RV anodal capture can occur at a high LV output during BiV pacing when it may cause slight ECG changes.
